MX-3610N ADJUSTMENTS AND SETTINGS 4 – 11
b. Color image density sensor (Image registration sensor F)
calibration (Method by SIM44-13)
1) Enter the SIM44-13 mode.
2) Open the front cover, and remove the waste toner box. Check
to confirm that the belt tension of the primary transfer unit is
released (the separation lever of the primary transfer unit is as
shown in the figure).
If the belt tension is not released, turn the separation lever to
the state shown in the figure.
When the transfer belt tension of the primary transfer unit is
released manually, turn on the power again after completion of
the work.
This procedure initializes the transfer roller to return it to the
home position.
3) Open the right paper transport unit, and remove the BK devel-
oping unit, the BK OPC drum unit, and the primary transfer
unit.
4)
Install the color image density sensor (image registration sen-
sor F) calibration jig (UKOG-0318FCZZ) to the sensor housing
section.
Engage the calibration jig with the projection of the sensor
housing, and slide it to the rear frame side.
5)
Close the right paper transport unit, and manually turn ON the
front door switch.
6)
Press [EXECUTE] key.
Color image density sensor (image registration sensor F) cali-
bration is automatically executed. When the operation is com-
pleted, the adjustment result is displayed and [EXECUTE] key
returns to the normal display.
If the adjustment is not completed normally, "ERROR" is dis-
played.
When an error occurs, the adjustment result is not revised.
In that case, check the following sections for any abnormality.
If any abnormality is found, repair and execute calibration
again.
* Color image density sensor (image registration sensor F)
* PCU PWB
* Image sensor calibration jig (dirt, scratch, discoloration)
* Image density sensor standard reflection plate (dirt, scratch,
discoloration)
The message is displayed, indicating that the jig is removed
and the primary transfer unit is installed.
7)
Remove the jig and install the BK developing unit, the BK OPC
drum unit, and the primary transfer unit, and close the right
paper transport unit.
8)
[EXECUTE] key is pressed again.
The image sensor calibration jig must be stored at lower tempera-
tures and low humidity without external lights.
When this adjustment is executed, perform the ADJ10B copy/
printer color balance adjustment with SIM46-74.
